BoLT.

To all whom it may concern:

Be it known that'I, FRANK P. PFLEGHAR, a citizen of the United States, and resident of New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Bolts, of which the following is a specification.

My invention relates to bolts and more particularly to bolts for use in vehicles such, for example, as automobiles, where it becomes desirable to manipulate the bolt from either the inside of the vehicle or outside as the case may be.

A practical embodiment of my invention is represented in the accompanying drawings in which Figure 1 is a view in side elevation showing 'fthe bolt applied to its support and in 'its thrown back or open position, Fig. 2 is a view of the same in front end elevation showing its support in edge elevation, Fig. 3 is a l -=horizontal section in the plane of the line e section through the same in the plane of the line DD of Fig. 7, Fig. 9 is an end view of the opposite bolt operating sleeve and handle, Fig. 10 is an end view of the intermediate connection between the two handles, Fig.. 11 is a view of the bolt in side elevation in detail, and Fig. 12 represents an edge and face view of the locking spring.

The part which carries the bolt and from the inner and outer sides of which the bolt is intended to be operated, is denoted by 1. On one side of the part 1, near its front edge, there is located a faceplate 2 which is prefer ably let into the part 1 the thickness of the plate, and this may be secured in position by means of screws, four screws 3 being here shown for securing it in position.

One of the bolt operating handles 4 has its shank which may consist of a short disk, seated in a keeper 5 by means of an under-cut 6 so as to permit the handle 4 to rotate a half revolution to throw the bolt forward and backward. The keeper 5 is secured to the outer side of the face plate 2 conveniently by means of spurs 7 which pass through holes 8 kSpecification of Letters Patent.

Application led September 28, 1905.

Patented March 1o, 190s.

Serial No. 280,434.

in the plate, the free ends of the spurs 7 being upset to hold the keeper locked to the bolt. The inner face of the shank of the handle 4 is provided with a short circular projection 9 located eccentrically on its face and this projection works in a shallow transverse slot or recess 10 in the bolt 11 to throw the bolt forward and backward as the handle 4 is turned.l

In order to bring the bolt under the con trol of the handle on the opposite side of the part 1, I provide an intermediate spindle 12, This spindle 12` projects through the part 1 and is provided on its end forward of the handle 4, with a central pin 13 which enters a hole 14 centrally in the shank of the handle 4 and with a pin 15 eccentric to the pin 13 which enters a hole in the shank of the handle 4. The hole 16 is here shown as located near the edge of the eccentric projection 9 which operates the bolt. v

The face plate 2 is provided with a central opening 17 for the rece tion of the enlarged inner end of the spind e 12 from which the pins 13 and 15 project and around the spindle 1.2 and bearing against the bolt 11, there is located a circular spring 18, the said spring as shown in Fig. 12, being provided with apair of ears 19, 20, diametrically disposed and projecting outwardly from its edge, which ears are intended to seat in recesses 21, 22, at the edge of the opening 17 in the face plate, while noses 23, 24, on the outer face of the spring 18 conveniently formed by bending the spring as shown in Fig. 12, seat in slots 25 and 26 formed on the op osite edges of the enlarged head of the spind e 12 to hold the spindle and hence the bolt against accidental displacement when in its full locked position or full open position. The spindle 12 is provided with a feather 27 extending longitudinally 4along one side thereof, which feather is received in a groove 28 formed in the wall of the tubular shank 29 of the o p osite handle 30. The handle 30 is made ast to and rotates in a face late 31 conveniently by swaging the col ar 32 on to its shank to lock the face plate 31 between the collar and handle and when the escutcheon 31 is secured to the back of the part 1, the handle will be secured in position.

In assembling the parts, the hollow shank 29 of the handle 30 is slid on to the spindle 12, the feather 27 occupying the groove 28 in the shank and thus the two handles are locked together so that when either one is turned,

the shank of the handle 4 with its eccentric 9 will be turned and hence the boltwill be thrown in the one way or the other de ending upon the direction in which the hand es are turned. This structure admits of throwing the bolt from one side or the other at pleasure while a single spring serves to lock it against unintentional displacement.

It will further be observed that the eccen tric 9 which operates the bolt is so located that it will be on center with respect to the longitudinal axis of the bolt when lthe bolt is at the eXtreme advance or eXtreme return movement, so that no pressure on the bolt itself can eiiect its displacement when in either of these two positions.

It is obvious that changes might be resorted to in the form and arrangement of the several parts without departing from the spirit and scope of my invention; hence I do notI wish to limit myself strictly to the structure herein set forth, but

What I claim as my invention is:

1. The combination with a longitudinally sliding bolt and a handle provided with a projection eccentrically located thereon for operating the bolt, of a second handle oppositely disposed with respect to the first named handle and connected with the iirst named handle for operating the said handle and hence the bolt. l 2. The combination with alongitudinally sliding bolt and a handle provided with a projection eccentrically located thereon for operating the bolt, of an oppositely disposed handle and an intermediate spindle connecting the shanks of the two handles to cause them to operate in unison.

3. The combination with alongitudinally reciprocating bolt and a handle having a projection eccentrically located thereon lor operating the bolt, of an intermediate spindle having a connection with the shank o'l" said Ahandle at a distance from its axis and a second handle having its shank connected with the spindle at a distance from its axis to rotate the spindle and hence the i'irst named handle and bolt.

4. The combination with a reciproeating bolt and a handle provided with a projection eccentrically located thereon for operating the bolt, ol a spindle provided with a pin projecting from its face in axial alinement with the first named handle and with a second pin projecting from its liaee at a distance from the axis thereof and a second handle provided with a shank adapted to receive said spindle and means for locking said shank to the spindle.

5. The combination with a reciprocating bolt, and a handle provided with a projection eccentrically located thereon for operating the bolt, of a spring housed between thc shank of the handle and the bolt support, the said spring and the handle being provided the one with projections and the other with recesses for frictionally holding the bolt in either its advanced or withdrawn position.

In testimony that I claim the foregoing as my invention, I havesigned my naine in presence of two witnesses, this 21st day of Sept., 1905. l
